Engine Diagnostics

A fault code is a starting point, not a parts order. Garage 46 investigates engine concerns, explains what the testing shows and quotes the next step before repair work begins.

Start with the symptoms and vehicle history

Describe what happens, how often and under which conditions. A cold-start concern can be different from a fault that appears after a long drive. Recent repairs, battery issues and modifications are useful context, even if they seem unrelated to the current warning light.

Testing beyond the code reader

A stored code describes a condition detected by the vehicle; it does not automatically prove that the part named in the code needs replacing. We investigate the cause and discuss the findings, including when more testing is needed to narrow down an intermittent concern.

Separate diagnosis from the repair

Diagnostic work establishes what to do next. Once the concern has been assessed, we explain the proposed repair and its cost. If the symptoms cannot be reproduced during the appointment, we discuss what was checked and what information would help the next investigation.

Before you book

Engine Diagnostics questions.

Does a check engine light identify the failed part?

No. Codes and symptoms guide the investigation, but further checks may be needed before the cause and appropriate repair can be confirmed.

Can you diagnose an intermittent problem?

Describe exactly when it happens and provide previous reports if available. The shop can discuss a testing plan; an intermittent fault may require more than one assessment to reproduce.

Is the repair included in the diagnostic quote?

Diagnosis and repair are separate scopes unless the shop explicitly quotes them together. Findings and proposed repair costs are explained before you authorize further work.
